Abstract

A method for warp knitting a narrow clasp fastener carrier tape having a strong selvage. A three guide bar construction is employed in which the front guide bar knits a pillar stitch and the middle guide bar performs shogging and lapping movements over two or more needles, with the back bar "laying-in" over three or more needles.
